ST. PIRAN FORMATION [Walcott, 1908a, p. 4] : 



la. Siliceous and arenaceous greenish-colored shales in layers i to 

 3 inches in thickness, interbedded in shaly and thin-bedded 

 gray and brownish gray sandstone, with a thick layer of 

 compact, gray sandstone near the top 68 



lb. Irregularly bedded brownish, dirty gray, and occasionally pur-

The general dip of the strata is to the northwest 20° ; strike, north 30° east.
